' To all whom it may concern:

The perforated sheet is placed on the sheet on whichthe design, letter, 850., is to be produced, and an inked roller ispassed over the sheet A, and the ink passes through the aperture orperforations upon the sheet below the perforated sheet. In casea mistakehas been made, the perforations can be closed by rubbing the wax withthe thumb-nail or an instrument.
